asymmetrical claws, the larger of which is typically capable of producing a loud snapping sound :
disproportionate large claw, larger than half the shrimp's body. The claw can be on either arm of the body,
and unlike most shrimp claws does not have pincers at the end. Rather, it has a pistol-like feature made of two parts.
A joint allows the "hammer" part to move backward into a right-angled position.
When released, it snaps into the other part of the claw, emitting an enormously powerful wave of bubbles capable of stunning larger fish
and breaking small glass jars.
